What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Participants With Solicited Local and Systemic ARs	Solicited ARs (local and systemic) were collected in the electronic diary (eDiary). Local ARs included: pain at injection site, erythema (redness) at injection site, swelling/induration (hardness) at injection site, and localized axillary swelling or tenderness ipsilateral to the injection arm. Systemic ARs included: headache, fatigue, myalgia (muscle aches all over the body), arthralgia (aching in several joints), nausea/vomiting, rash, body temperature (potentially fever), and chills. Solicited ARs (local and systemic) considered causally related to injection were graded 0-4; lower score indicates lower severity and a higher score indicates greater severity. Note, not all solicited ARs were considered adverse events (AEs). The Investigator reviewed whether the solicited AR was also to be recorded as an AE. Summary of serious AEs (SAEs) and nonserious AEs ("Other"), regardless of causality, is in Reported "Adverse Events" section and presented by Phase/dose group.	7 days after vaccination
Number of Participants With Unsolicited AEs	An AE was defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug related. A treatment-emergent AE (TEAE) was defined as any event not present before exposure to vaccine or any event already present that worsens in intensity or frequency after exposure. Any abnormal laboratory test result (hematology, clinical chemistry, or prothrombin time [PT]/partial thromboplastin time [PTT]) or other safety assessment (for example, electrocardiogram, radiological scan, vital sign measurement), including one that worsens from baseline and is considered clinically significant in the medical and scientific judgment of the Investigator. A summary of SAEs and all nonserious AEs ("Other") reported up to the end of the study, regardless of causality, is located in the Reported "Adverse Events" section and presented by each Phase and dose group separately.	Up to 28 days after vaccination
Number of Participants With SAEs, AEs of Special Interest (AESIs), Medically Attended AEs (MAAEs)	An SAE was defined as any AE that resulted in death, is life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in disability/permanent damage, was a congenital anomaly/birth defect, or was an important medical event. AESIs included thrombocytopenia, new onset of or worsening of the protocol specified neurologic diseases, anaphylaxis, and myocarditis/pericarditis. An MAAE is an AE that leads to an unscheduled visit to an healthcare practitioner. This would include visits to a study site for unscheduled assessments (for example, abnormal laboratory follow-up, and/or COVID-19 and visits to healthcare practitioners external to the study site (for example, urgent care, primary care physician). A summary of SAEs and all nonserious AEs ("Other"), regardless of causality, is located in the Reported "Adverse Events" section and presented by each Phase and dose group separately.	Up to 6 months (end of study)
Phase 1/2: Geometric Mean Titer (GMT) of Anti-Hemagglutinin (HA) Antibodies at Day 29, as Measured by Hemagglutination Inhibition (HAI) Assay for Vaccine-Matched Seasonal Influenza A and B Strains	Seasonal influenza A included H1N1 and H3N2 and seasonal influenza B strains included Victoria-lineage and Yamagata-lineage. GMT 95% confidence interval (CI) was calculated based on the t-distribution of the log-transformed values then back transformed to the original scale for presentation.	Day 29
Phase 2 NH: GMT of HA Antibodies at Day 29, as Measured by HAI Assay for Vaccine-Matched Seasonal Influenza A and B Strains	Humoral immunogenicity relative to that of the active comparator (afluria quadrivalent) was assessed against vaccine-matched Influenza A and B strains at Day 29. Seasonal influenza A included H1N1 and H3N2 and seasonal influenza B strains included Victoria-lineage and Yamagata-lineage. GMT 95% CI was calculated based on the t-distribution of the log-transformed values then back transformed to the original scale for presentation.	Day 29
Phase 2 Extension: GMT of HA Antibodies at Day 29, as Measured by HAI Assay for Vaccine-Matched Seasonal Influenza A and B Strains	Humoral immunogenicity relative to that of the active comparator (afluria quadrivalent) was assessed against vaccine-matched Influenza A and B strains at Day 29. Seasonal influenza A included H1N1 and H3N2 and seasonal influenza B strains included Victoria-lineage and Yamagata-lineage. GMT 95% CI was calculated based on the t-distribution of the log-transformed values then back transformed to the original scale for presentation.	Day 29
Phase 1/2: Percentage of Participants With Seroconversion, as Measured by HAI Assay for Vaccine-Matched Seasonal Influenza A and B	Seasonal influenza A included H1N1 and H3N2 and seasonal influenza B strains included Victoria-lineage and Yamagata-lineage. Seroconversion at a participant level was defined as (a) if lower limit of quantification (LLOQ) was 1:10, a post-baseline titer ≥1:40 if baseline was <1:10 or a 4-fold or greater rise from baseline if baseline was ≥1:10 in anti-HA antibodies; or (b) if LLOQ was >1:10, a post-baseline titer ≥4 x LLOQ if baseline was <LLOQ, or 4-fold or greater increase from baseline if baseline was ≥LLOQ in anti-HA antibodies.	Day 29
Phase 1/2: Geometric Mean Fold-Rise (GMFR) of Anti-HA Antibodies at Day 29, as Measured by HAI Assay for Vaccine-Matched Seasonal Influenza A and B Strains	The GMFR measures the changes in immunogenicity titers or levels from Baseline within participants. Seasonal influenza A included H1N1 and H3N2 and seasonal influenza B strains included Victoria-lineage and Yamagata-lineage. 95% CI was calculated based on the difference in the log-transformed values for GMFR, then back transformed to the original scale for presentation.	Day 1 (Baseline), Day 29
Phase 2 NH: Percentage of Participants With Seroconversion, as Measured by HAI Assay for Vaccine-Matched Seasonal Influenza A and B	Humoral immunogenicity relative to that of the active comparator (afluria quadrivalent) was assessed against vaccine-matched Influenza A and B strains at Day 29. Seasonal influenza A included H1N1 and H3N2 and seasonal influenza B strains included Victoria-lineage and Yamagata-lineage. Seroconversion at a participant level was defined as (a) if LLOQ was 1:10, a post-baseline titer ≥1:40 if baseline was <1:10 or a 4-fold or greater rise from baseline if baseline was ≥1:10 in anti-HA antibodies; or (b) if LLOQ was >1:10, a post-baseline titer ≥4 x LLOQ if baseline was <LLOQ, or 4-fold or greater increase from baseline if baseline was ≥LLOQ in anti-HA antibodies. 95% CI was calculated using the Clopper-Pearson method	Day 29
Phase 2 Extension: Percentage of Participants With Seroconversion, as Measured by HAI Assay for Vaccine-Matched Seasonal Influenza A and B	Humoral immunogenicity relative to that of the active comparator (afluria quadrivalent) was assessed against vaccine-matched Influenza A and B strains at Day 29. Seasonal influenza A included H1N1 and H3N2 and seasonal influenza B strains included Victoria-lineage and Yamagata-lineage. Seroconversion at a participant level was defined as (a) if LLOQ was 1:10, a post-baseline titer ≥1:40 if baseline was <1:10 or a 4-fold or greater rise from baseline if baseline was ≥1:10 in anti-HA antibodies; or (b) if LLOQ was >1:10, a post-baseline titer ≥4 x LLOQ if baseline was <LLOQ, or 4-fold or greater increase from baseline if baseline was ≥LLOQ in anti-HA antibodies. 95% CI was calculated using the Clopper-Pearson method	Day 29
